Title: Information transfer system
Inventor: SHINAGAWA AKIO
IPC: G06F3/00
Filed: 1979-02-16
Abstract: PURPOSE: To make it possible to improve reliability while continuing information transfer even if a few transmission lines would get out of order during data transfer, by connecting one transmission line each to a buffer correspondingly.  
     CONSTITUTION: Now, if transmission line βp would get out of order, a group of data which is being transferred is resent, but data corresponding to transmission lines βp+1Wβh are read out first and transmitted. Then, control circuit γpj is opened to shift the content of FF pj WFF p+1 j, it is transmitted by using control circuit βp+1, and data corresponding to transmission lines β1Wβp-1 are further transmitted. To write data to each FF next, FF pj  is avoided unless transmission line βp recovers from the fault, and transmission is advanced by using another transmission line. Thus, information transfer can be continued.

Title: Video signal correction circuit
Inventor: KAMIKO MITSUO
IPC: G09G3/18
Filed: 1993-01-07
Abstract: PURPOSE:To correct a video signal corresponding to the transmissive characteris tic of a liquid crystal, and further, to stably supply the video signal with simple constitution and without being affected by the level of the video signal and the change in temperature. CONSTITUTION:A transistor 30 is turned off when V0>E1 and the load resistance of the transistor 7 becomes a main resistor 8. Further, the transistor 30 is turned on when V0<E1 and the load resistance of the transistor 7 becomes the load by the parallel connection of the main resistance 8 with an auxiliary resitor 31. Thus, since the video signal appearing at an output terminal 10 shows a steep characteristic at a voltage E1 or above and further becomes a log curve at the voltage V1 or below, the video signal is corrected corresponding to the transmissive characteristic of the liquid crystal.

Title: Plasma etching device
Inventor: SATOU MASAAKI
IPC: H01L21/3065
Filed: 1981-02-09
Abstract: PURPOSE: To prevent damaging upon elements and the change in properties of resist and to improve treating capacity in a counter electrode type plasma etching device by connecting two high frequency electric power sources of different frequencies.  
     CONSTITUTION: The inside of an etching device is evacuated and a reactive gas is introduced therein and is maintained under prescribed pressure. High frequency electric power of a high frequency is applied from a high frequency electric power source 7 to an anode electrode 3, so that plasma is generated between the electrode 3 and a cathode electrode 2. Similarly, high frequency electric power of the frequency lower than that of the power source 8 is applied to the electrode 2 or the electrode 3 so that plasma is generated. At this time the plasma  density is increased or decreased by increasing or decreasing the high frequency  electric power to be applied to the electrode 2, thereby changing the ion energy  impinging upon the object to be etched. By this mechanism, a high etching rate  is obtained and the treating capacity of etching is improved.

Title: Parallel/serial converter
Inventor: NODA SHUNEI
IPC: H04L13/10
Filed: 1985-01-31
Abstract: PURPOSE:To select and send a character synchronizing system or a flag synchronizing system easily through a communication LSI by controlling the operation of 0-insersion counter on the basis of the status of a control FF latching a control signal at the input of parallel data to a parallel/serial converting circuit. CONSTITUTION:When a control input signal 102 is 'L', the output 103 of the control FF2 is also 'L' and the output of a gate G7 is always held at 'H' to inhibit the operation of the 0-insersion counter 4. Thereby, a carry-out signal 104 is not outputted from the counter 4 and the counter 4 is held at 'L'. Consequently, an input to an in-bit terminal (iNH) of a transmission counter 3 is invalidated, the output of the gate G9 is turned to 'H', the output of a gate G2 becomes equal to a carrier signal 105 outputted from a counter 3 and the outputs of gates G4, G8 become equivalent to the other input signals respectively. When the signal 103 is 'H', one 'L' is inserted into a serial output signal 107 every continuous 5 'H's. During said operation, the operation of the counter 3 and the circuit 1 is interrupted.

Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To verify a drying effect by enabling a ventilation means to display humidity that is detected by an effect humidity detection means for detecting the humidity of the fresh air being blown into internal space. SOLUTION: Standby is made until an operation switch SW13 is pressed by judging whether a user has pressed the operation switch SW13 that is pressed for drying an area below the floor. When the operation switch SW13 is pressed, a ventilation means 14 blows the fresh air to an area below the floor.

Then, until the operation switch SW13 is pressed again, the detection of the humidity of the fresh air to be blown to the area below the floor by the ventilation means 14 and the display of the detected humidity are repeated, thus displaying the humidity of the fresh air to be blown to the area below the floor by the ventilation means 14 on a display means 16 and hence enabling the user to determine the humidity of the fresh air to be blown to the area below the floor and verify a drying effect.
